GeForce RTX 2070 Super vs Radeon RX 580

Intro

Compare those specifications to the Radeon RX 580, which makes use of a 14 nm design. AMD has set the core speed at 1257 MHz. The GDDR5 RAM is set to run at a speed of 2000 MHz on this particular model. It features 2304 SPUs along with 144 TAUs and 32 ROPs.

Radeon RX 580		185 Watts
GeForce RTX 2070 Super		215 Watts
	Difference: 30 Watts (16%)

Memory Bandwidth

In theory, the GeForce RTX 2070 Super should perform quite a bit faster than the Radeon RX 580 in general. (explain)

GeForce RTX 2070 Super		458752 MB/sec
Radeon RX 580		262144 MB/sec
	Difference: 196608 (75%)

Texel Rate

The GeForce RTX 2070 Super will be a lot (more or less 42%) better at AF than the Radeon RX 580. (explain)

GeForce RTX 2070 Super		256800 Mtexels/sec
Radeon RX 580		181008 Mtexels/sec
	Difference: 75792 (42%)

Pixel Rate

The GeForce RTX 2070 Super will be a lot (more or less 155%) more effective at full screen anti-aliasing than the Radeon RX 580, and also should be capable of handling higher screen resolutions more effectively. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 62496 (155%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
